EXCAVATOR-BEAM.

.To all whom it may concern;-

Be it known that I, LOUIS AnsENE DesY, a sub ect of the King of Great Britain, residing at the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Ex cavator-Beams; andI do hereby declare that the following is afull, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which itappertains to make and use the same.

My invention relates to excavator-beams. The object of my invention is to provide means for mounting a bucket on a beam so that the bucket may be shifted axially of the beam and which will permit the attachment of either a clam-shell or an orange-peel bucket. I

A further object is to provide a beam constructed to permit the assage therein of the actuating-r0 es of the ucket.

More specifically, the object is to provide means for detachably securing a bucket on a.

hollow beam, so that the bucket may be shifted axially of the beam or easily detached. A further object is to provide a beam with an open side adapted to permit the actuating sheave to project therein, to permit a wide range of vertical adjustment of the beam with relation to its raising and lowering means; and my invention consists of the construction, combination, and arrangement of parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming horizontal section on line 6 6 of F ig. 3 looking in the direction indicated by the arrow. Fig. 7 is a horizontal section on line 7 7 of Fig.3 looking in the direction indicated by the arrow. Fig. 8 is a plan view of a clamshell-bucket-attaching means. Fig. 9 is a side elevation, partly in section, of a clamshell-bucket-attaching means. Fig. 10 is an end elevation, partly in section, of a clamshell-bucket-attachin means. bottom plan view, 0 a circular attaching member adapted for use with either a clamshell or an orange-peel bucket. Fig. 12 is a side elevation, partly in section, of the attaching member. Fig. 13 is a plan view of an orange-peel-bucket-Supporting member; and Fig. 14 is a side elevation, partly in section, of an orange-peel-bucket-supporting member.

Referring to the drawings, 1 designates a pair of vertically-disposed channel-iron members connected at one side by a plate 2, which extends from the lower ends thereof to the upper ends, leaving the opposite side open. Disposed around the lower ends of the channel-iron members 1 and the plate 2 are straps 3, which are rivetedsolidly to said members ,1 and 2; Projecting into the angles of the channel members 1 are the upper ends of angle-irons 4, which are riveted to said straps 3 and have their lower ends connected by means of the braces 5. (Shown in Fig. 7 only.)

Slidably disposed on the beam formed by .the angle-iron members 4 and hereafter referred to as the "beam is a casing 6, provided with ears '7. Disposed around the beam below the casing '6 is a circular flanged member 8, adapted to be connected to the easin 6 by means of the fastening members 9, which may be disposed through any of the openings 10.which are arranged, in .a circle in the member 8. By this construction the member 8 may be shifted axially of the easing '6, which is slidably disposed on the beam,

so that it will not rotate therewith, the

casing being preferably of angle-iron or similar constructlon.

Formed on the under side of the axiallyadjustable member 8 are bearings 11, adapted to receive the upper ends of the links 12, the lower ends of which links are pivoted, as at 13, to the outer edges of either a clamshell bucket A or an orange-peel bucket B. In either event the link 12 is of bifurcated construction, although the bifurcation in the form shown in Fig. 3 is shorter than that shown in the other figures, 'as the oints of pivotal support for the clam-she bucket are more widely se arated than for an orange-peel bucket; a so, in the form for a Fig. 11 is a ICC clam-shell bucket only two points of pivotal what I claim as new, and desire to secure-by 533F011, are needed for the upper'ends ofthe s 12; but the member 8 is provided with four points of pivotal support, so as to be adapted for use 1n connection with an orange.- peel bucket, which needs more than two olnts of support for theupper ends of the inks i, I V

Fixed to the lower end of the beam'is a shoe l4/provided with a horizontal flange 15, against which is dis osed a bucket-supporting member 16, a

bolts 17, disposed the bucket-supporting member, so that the bucket-supportmg member may be easily detached or adjusted axially of the beam.

In both of the forms of bucket-supporting members illustrated there are provided thereon depending ears 'havin openings 20 therein ada ted to receive the pins 21, by means of w ich the leaves of the clamshell bucket may be ivotally secured orby means of which the inks 21 of the orangepeel bucket B maybe'held. When an orangepeel bucket is used, the arms 23 are pivoted to the links 21 in orderto limit the movement of the leaves of the bucket when they are actuated on their pivotal supports 13.

Disposed thropgh' the casing 6 and through the lowen end of the beam is a horizontal shaft 24, carrying the sheaves 25. Carried by the lower end of the beam. are lower sheaves 26, corresponding to the sheaves 25. Said sheaves lie within the beam and have passed thereover an operating-rope 27, "the lower end of which is connected to the securing member, 28 on the outside of the beam adjacent its lower end. A suitable elevating-rope 29 is secured to an eye 30 Within the beam, and both of said ropes are disposed over the sheaves 31, Which'may be carried by a suitable boom or other actuating mechanism, said sheaves 31 projecting through the open space 32 left on the side of the beam opposite the plate 2, so that the beam may be carried upward until the straps 3 contact with the sheaves 31.

On account of the circular arrangement of the openings 18 in the bucket-supporting members 16 and the corresponding circular arrangement of the openings 10 in the bucket-attaching member 8 it should be evident that either of the buckets A or B may be easily attached and removed and may be easily shifted axially of the beam. In the operation of the invention the beam and its connecting arts are raised or lowered by means of the rope 29, while the bucket is opened or closed by means .of the rope 27, the function of the ropes and sheaves, in combination with the movable parts of the bucket, being the same as in my allowed United States case, No. 291,448.
